摘要: 我国核电机组堆型众多,来源广泛,这些引进堆型的源项在我国应用中还存在一些问题。源项设计是否合理,直接影响到排放源项的准确性和环境影响评价源项的合理性。本文通过分析不同堆型源项在我国应用中存在的问题,研究如何构建我国核电厂通用的一回路源项和排放源项框架体系,为解决国内核电厂源项计算中长期存在的问题,也为我国华龙一号和CAP1400堆型的源项计算提供技术基础。

Abstract: There are still some problems in the application of original source terms in operating nuclear power plants imported from different countries, including France, USA and Russia, because of their different regulatory requirements and safety considerations. Some unreasonable design of source terms will directly affect the accuracy of emission source terms and rationality of source terms for environmental impact assessment. In order to solve these problems, frameworks for primary circuit source terms and emission source terms are studied, established and described, to which could provide a technical basis for the calculation of source terms in Hualong-1 and CAP1400 reactors.

Key words: nuclear power plant, primary circuit source terms, emission source terms, framework system, fission products
